DIL switch settings
The mode of operation is set up using the DIL switches SW4 and SW5.
SW POSITION FUNCTION SETTING
SW4, 1 Selects either remote
operation or local operation Off = local
On = remote
SW4, 2 Selects interface type Off = G.703
On = G.704
SW4, 3 Allows unframed operation On = unframed operation not permitted
Off = unframed operation permitted
1
SW4, 4
SW4, 5 Sets up operation of X.
When X.21/V.11 interface
set.
X = I lead
Y = C lead.
When V.35 interface set
X = FLAG 1 O/P,
Y = FLAG 3 I/P
SW4, 4 = off, SW4, 5 = off,
X follows Y
SW4, 4 = on, SW4, 5 = on,
X follows Carrier
SW4, 4 = off, SW4, 5 = on,
X = active
SW4, 4 = on, SW4, 5 = off,
X = inactive
SW4, 6 Sets G-Converter to
permanent
Transparent mode 2048kbps Off = permanent straight through
2
On = framed/unframed
SW4, 7 Sets G.70x TX off if no
G.703 RX detected Off=G.703 TX enabled always.
On = G.703 TX disabled in the event of
G.703 RX not being present
4
SW4, 8 Use External Clock
3
On = Use external clock. Off = do not
use external clock.
SW5,1 Enables Remote Loopback
function
Off = Remote loop back enabled.
On = Remote loop back disabled
SW5, 2
SW5, 3 Sets up operation of FLAG 2
O/P “
X “ when set for V.35
interface
SW5, 2 = off, SW5, 3 = off,
X follows Flag3 I/P
SW5, 2 = on, SW5, 3 = on,
X follows Carrier
SW5, 2 = off, SW5, 3 = on,
X = active
SW5, 2 = on, SW5, 3 = off
X = inactive
SW5,4 Sets Autobauding on or off Off = Autobauding not selected
On = Autobauding selected
N.B for Autobauding SW4,8 must be
set to on
